LED lamp string sequencing method, LED lamp string system and LED lamp thereof

Abstract

The invention discloses an LED lamp string sequencing method, an LED lamp string system and an LED lamp thereof. The LED lamp string sequencing method comprises steps that (a) a control module is usedfor providing pulse wave signals for an LED lamp string; (b) LED lamps with the current sequence characteristics of the LED lamp string at a first rising edge or a first falling edge of a pulse wavesignal are obtained; (c) the LED lamps self-memorize the current sequence; (d) a self state of the LED lamps in the current sequence is changed so as not to generate characteristics of the current sequence; and (e) the steps (b) to (c) are repeated to obtain the sequence of the LED lamps. The method is advantaged in that a simple impedance principle is utilized, so the LED lamp string does not need to record addresses in advance before leaving a factory, and a user can replace the LED lamp by himself / herself when the LED lamp is damaged.

Description

technical field [0001] The present invention relates to a method for sequencing LED light strings, a self-sequencing LED light string system and its LED lights, especially a method for sequencing LED light strings using instantaneous impedance to arrange the sequence of LED lights, LED Light string system and its LED lights. Background technique [0002] LED lights refer to lamps that use light-emitting diodes (LEDs) as light sources, and are generally made of semiconductor LEDs. The service life and luminous efficiency of LED lamps can reach multiples of incandescent lamps, and are much higher than those of integrated fluorescent lamps. Therefore, more and more products on the market use LED lights to replace traditional fluorescent tubes. Among them, because the LED light contains the characteristics of the controller, the LED lights are connected in series to form an LED light string, and then the address of each LED is set by recording, so that the LED lights in the LE...

Problems solved by technology

[0003] However, because the address recording of the LED lights in the LED light string must use a special recording device, it must be recorded by the manufacturer after sorting the current order of the LEDs before the LED light string leaves the factory, in order to make the LED light string leave the factory That is, it has the function of sequencing, otherwise it is impossible to control the LED light string in an orderly manner

Therefore, before the LED light strings leave the factory, the manufacturer must carry out the cumbersome procedures of sorting the LED lights and burning them sequentially, resulting in inconvenience and time-consuming product manufacturing.

Moreover, since the address of the LED light is pre-recorded before leaving the factory, if the LED light in the light string fails after the LED light string leaves the factory, the user cannot replace the LED light by himself. Maintenance of light string 20

As a result, if any LED lights are damaged, the entire set of LED light strings can only be scrapped, or the entire set must be sent back to the original factory for repair, resulting in inconvenience in use
